DeNA and Mobage are preparing to launch a new Attack on Titan: Jiyuu e no Houkou (Roar to Freedom) smartphone game for Japanese Android and iOS devices this winter. In the Clash of Clans like game, the survey corp must fortify towns outside the main walls and exterminate attacking Titans. Resources can be used for armor to equip the soldiers, including game original character Fereta.
The unfamiliar face joining Eren, Mikasa and Levi seems to have some attire that doesn't really conform to military regulations.
Incentive in-game items are being offered for early registration.
